AVR laser projector

This is another interesting project on a breadboard. It uses an idea of rotating mirrors that create laser video effect. It is able to generate 16×16 dots, 30fps monochromatic video projections.

Projector uses mirror drum which was the hardest part to calibrate, as they have to be tilted differently in order to form beam lines like on TV screen. And of course it has to be synchronized with microcontroller to generate frames. This small theatre even have a servo motor which rises and lowers projection screen. This gives really cool effect. Turnt the lights off it’s show time!
